taco stoped working

its a 1998 T401 kenworth with a cummins M11 celect plus, i have just found out that the taco gets its power from the ECM and also has a ground wire, but thats all i can find out so far. im thinking that the sensor that the ECM gets its info from may be faulty?? or maybe a bad earth from the taco?

 

thanks, i will check those things.

 

i can understand your logic, but no its taco. we have some very weird sayings here in oz, like fair dinkim, flat out like a lizzard drinking, bloody oath mate, etc

 

glad u got a laugh superhauler. have a great easter mate

 

update - i checked the bellhousing and there is no sensor so the ECM must run off the EPS which is a four wire EPS. when i cranked the engine over the taco needle moved a few times while cranking, but did not work once the engine fired. ? any ideas?

 

yep its looking like a trip to cummins lol, just got to find the time when they r open and find my stash of gold bullion to pay them.
